Three-degree-of-freedom vibration screening device capable of being leveled

The utility model discloses a three-degree-of-freedom vibration screening device capable of leveling, which is mainly used for screening straw husks, seeds and the like and comprises a frame, a leveling device, a three-degree-of-freedom vibration device and a controller. The leveling device is installed on the machine frame and used for adjusting the balance of the double-layer sieve tray, the three-degree-of-freedom vibration device is installed at the bottom of the machine frame to enable the double-layer sieve tray to move in a three-degree-of-freedom mode, and the problems that an existingvibration sieve cannot efficiently sieve various mixtures, and a sieve net is prone to being blocked are solved. The three-degree-of-freedom vibration mode can greatly solve the problem that the screen is blocked, and the separation efficiency is improved; the double-layer sieve tray can be freely replaced, can sieve various mixtures, and is expected to be popularized in a large area. 本实用新型公开了一种可调平三自由度振动筛分装置，主要用于筛分秸秆谷壳与种
